Abstract: A search for neutral non-standard-model Higgs bosons decaying to two muons is presented. The search is performed in the context of the minimal supersymmetric standard model, using proton-proton collisions data recorded by CMS at the CERN Large Hadron Collider at a center-of-mass energy of 13 TeV. The integrated luminosity is 35.9 fb $^{-1}$ . The search is sensitive to neutral Higgs bosons produced via gluon fusion process or in association with a $\mathrm{b\bar{b}}$ quark pair. No significant deviation from the standard model expectation is observed. A 95% confidence level upper limit is set in the context of the $m_{\rm h}^{\rm mod+}$ and hMSSM scenarios on the parameter $\tan\beta$ as a function of the pseudoscalar A boson mass, in the range from 130 to 600 GeV. The larger collected luminosity and the higher center-of-mass energy exclude a larger $m_{\mathrm{A}}$ - $\tan\beta$ region, compared to what was obtained at 7 and 8 TeV by a similar analysis. The results are also used to set a model-independent limit on the product of the branching fraction for the decay into a muon pair and the cross section for the production of a scalar neutral boson, either via gluon fusion, or in association with b quarks, in the mass range from 130 to 1000 GeV.
